DUMPlNG- CAR.

SPECIFICATION forming part of Letters Patent No. 425,607, dated April15, 1890.

Application filed October 9, 1888- Serial No. 287,652- (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM W. GREEN, of Chicago, county of Cook, andState of Illinois, have invented certain new and useful Improvements inDumping-Oars, of which the following is a full, clear, and exactdescription, that will enable others to make and use the same, referencebeing had to the accompanying drawings, forming a part of thisspecification.

The object of this invention is to secure the car-body to the bed-framein such a manner as to readily permit of the body or divisions thereofbeing tilted and the load discharged on either side, as will behereinafter set forth.

Figure 1 is a side elevation of a'car structure embodying my improvedfeatures; Fig.

2, a transverse section in plane 2, Fig. 1; Fig.

3, a broken-away detail of one of the standards supporting theWindlass-shafts; and Fig. 4, a sectional detail in plane 4, Fig. 3.

In the draWings,A represents the framingtimbers forming the car-bed. Thebody of the car consists of the three separate and independentcompartments or boxes B B B pro- Vided at each end with hinged end-gatesB B. These end-gates may be locked in place by means of the ordinaryslide-bolt a, arranged vertically. The locking device consisting of theverticalbolt a, having the inner ends of the horizontal companion bolts(1 a pivoted thereto and the outer ends engaging with the sides of thebox-compartment,is preferred, as it more firmly secures the end-gate inposition, and is thrown into and out of a locking engagement by thevertical movement of theprincipal bolt a.

The box compartment or compartments forming the car-body may be tiltedso as to discharge the load from either side of the car, as may berequired, by means of the mechanism that will now be described.

The car-body or each boX- compartment thereof is hinged to the bed-frameat each side by the transverse lever-hinges O O. The alternate ends ofthese companion levers are attached to the under side of the car-body bythe pivot-bolts a a (see Fig. 2,) while the opposite alternate ends arepivoted to the lugs a by the bolts a a the lugs being rigidly I boltedto the frame-timbers of the car structure. It will be understood thatthis system of lever-hinges is used in duplicate on both sides of thebox-compartments. This arrangement and manner of attaching the car-bodypermits of the box-compartments being tilted from either side of thecar, as shown in Fig. 2.

D represents a number of standards, (two being required for eachboX-co1npartment,) the lower ends of which are properly secured to thecar-frame, the upper ends terminating at some distance above thecar-body, and supports the Windlass mechanism employed in tilting thebody when discharging the load.

The upper ends of the standards D are provided with the horizontalrectangular slots 1), (see Figs. 2 and 3,) in which are placed theadjustable boxes 19', forming journal-bearings for the respective endsof the Windlass shaft or shafts D. Each of these shafts haswinding-drums D D mounted thereon. The upper ends of the Windlass cablesor chains D are properly secured to the winding-drums, the opposite hookends 12 detachably engaging with the lugs 12 b, rigidly secured to eachside and near the respective ends of the box-compartments, the hook endsof cable being shifted from the lugs at one end to the companion lugs atthe other end, in accordance with the side of the car itis intended todischarge the load from, the Windlass-shafts having a correspondingmovement in the rectangular slots b,

so as to bring the winding-drums into proper position and angle relativeto the ends of the box-compartments to insure a more direct lift.

The Windlass-shafts have each a worm gearwheeld mounted thereon. TheWorm-shaft d is provided with bearings d on the upper ends of thestandards D and engage with said gear-wheels. The worm-shafts havesquare ends to receive the hand-crank d by which means the motionnecessary to tilt the carbody is transmitted. By this arrangement theload may be discharged from either side of the car with the samefacility. The nature and simplicity of the improvement are such that aspecial car structure is not required, but may be used on the ordinaryplatformcar.

The object of dividing the car-body up into a number of compartments isto permit of the load being easily dumped by hand. Where it is intendedto employ power the car-body could be tilted as a whole with the samefacility, It is also obvious that the improvement 2.
